Application filed June 30,1906. Serial No. 324.252.

To all whom it may concern: I

Be it known. that I, GEORGE H. PREN- TIOE, a citizen if the UnitedStates of America, residing at Painesville, in the county of Lake andState of Ohio, have invented certain new. and useful Improvements inDevices for Preventing theCreeping of Rails; and I hereby declare thefollowing to be a full, clear, and exact description of the invention,vsiuch as will enable others skilled in the art to-which it pertains tomake and use the same. i

This invention relates to improvements in means for preventing thecreeping of rails.

The object of this'invention is to provide an 'antirail-creeping devicewhich is exceed- 1n ly,s1mple and durable in construction and re lablein its operation and comprises two metal bars, with one of the barsadapted to be secured in place at one side of the rail and terminatingin a Wedge-formin member, which projects forwardly in the irection inwhich the rail tendsto creep and is arranged withits larger end infront, and with the other bar adapted to extend under and transverselyof the rail and aforesaid wedge-forming member and provided-Withclampingjaws at the ends, with one of the jaws clam ing thewedge-forming member, against t e base of the rail at one of thelongitudinal edges of the base and with the other jaw clamping or griping the other longitudinal edge of the railase, so that any tendency ofthe rail to creep will tend to pull the railclamping bar forwardly andtend to still further tighten the grip of the aforesaid jaws.

With this object in view this invention consists in certain features ofconstruction and combinations of parts hereinafter described, andpointed out in the claims. In the accompanying drawings, Figure 1 is atop lan of a rail provided with my improve means for preventing thecreeping of the rail. Fig. 2 is a left-hand end view relaive to Fig. 1in section on line 2 2.

Referring to the drawings, A indicates the rail, and a the base of therail.

represents a tie arranged under and transversely of the rail andconstituting a rail-support. a

G represents a metal bar which rests upon the tie at one side of therail and extends transversely of the tie along the adjacent lontudinaledge of the base of the rail, The arG is spiked or otherwise secured tothe tie, as at 7L.

ranged at the outer side The bar Gr terminates in a wedgeforming member9, which projects longitudinally of the rail in the direction in-whichthe rail tends to creep and forwardly beyond the tie. It is almostsurperfiuous to remark that the rail tends to cree in the direction inwhich rolling stock is intended to move on the rail, and the arrow 0,marked upon the rail in Fig. 1, indicates the direction in which therolling-stocktravels.

The wedge-forming member with its larger end in front and bears 'againstand clam s or gri s the base of the rail at the adjacent ongitu inaledge of the base. indicates a rail-clamping bar, which is arrangedforward of the tie and parallel or approximately parallel with the tie;The ar K extends under and transversely of the rail and aforesaidwedge-forming member and is provided atone end with a jaw 70, whichprojects upwardly at theiouter side of and embraces the wedge and gripsand clamps the wed e against the base of the rail. ence the jawv andwedge-forming member 5] clamp the rail at one of thelongitudinal ed esof the rail-base, and the bar K is pro- 9 is arranged vi ed at itsopposite end with jaw K',-

grips the other longitudinal which clamps or ed e of the rail-base.

- t will be observed that the tendency of the rail to creep in thedirection indicated by the arrow 0 tendsto'pull the bar K forwardly fromthe tie, and consequently in the direction required to further tightenthe wedgeforming member 9 between the jaw la and the rail, so astotighten the of the rail-clamping bar K.

at I claim is- 1. The combination, with a rail, and a tie arranged underand transversely of the rail, of a bar arranged upon and transversely ofthe tie at one side rail, which bar is attached to the tie and has awedge-forming member which projects heyondthe tie in the direction inwhich the rail tends to creep and is arranged with its larger end infront, which wedge-forming member bears against the ad'acentlongitudinal edge of the base of the rail at the aforesaid side of therail, and a rail-clamping bar arranged under and transversely of therail and aforesaid wedgeforming member forward of the tie and providedat one end with a jaw arof and embracing the aforesaid wedge-formingmember instrumental in clamping the latter against the grip of the jawsand longitudinally of the aforesaid longitudinal edge, saidrail-clamping bar being provided at its opposite end with a jaw whichclamps or grips the other longitudinal edge of the rail-base so that antendency of the rail to creep will tend to pu l. the rail-clamping barforwardly and tend" to still further tighten the grip of the .jaws ofthe said bar.

2. The combination, with a rail, and a tie arranged under the rail, of abar arranged upon the tie at one side of the rail, which bar is attachedto the tie and has awedge-forming member which projects in the directionin which the rail tends to creep and is arranged with its larger'end infront, which wedge-forming member bears against the base of the rail atthe aforesaid" side of the rail, and a rail-clamping bar ari anged underforming member against the base of therail at the aforesaid side of therail, said railclamping bar being provided at its opposite end with ajaw which clamps or grips the railbase at the opposite side of the railso that any tendency of the rail to creep will tend to larger end infront, which wedge-forming pull the rail-clamping bar forwardly and tendto still further tighten the grip of the jaw of the said bar.

3. The combination, with a rail, and a tie arranged under the rail, of abar secured to the tie and having a wedgeforming member which projectsin the direction in which the rail tends to creep and is arranged withits member bears against one of the longitudinal. edges of the base ofthe rail, and a rail-clamping bar arranged under andtran'sversely of therail and aforesaid wedge-forming memher and provided at one end with ajaw which clamps the wedge-forming member against the aforesaidlongitudinal edge of the railbase, said rail-clamping bar being providedat its opposite end with a jaw which clamps or grips theotherlongitudinal edge of the rail-base so that any tendency of the rail tocreep will tend to pull the rail-clamping bar forward and tend to stillfurther tighten the grip of the awe of the said bar.

4 The combination, with a rail, of a suitably-supported bar arranged atone side and longitudinally of the rail, which bar projects in thedirection in which the rail tends to creep and is arranged with itslarger end in front, which wedge-forming member bears against the baseof the rail at the aforesaid side of the rail, anda rail-clamping bararranged under and transversely of the rail and aforesaid wedge-formingmember and provided at one end with a jaw which clamps the wedge-formingmember against the rail-base, said rail-clamping bar being provided atits opposite end with a jaw which clamps or grips the rail-base at theopposite side of the rai so that any tendency of the rail to creep willtend to pull the rail-clamping bar forwardly and tend to still furthertighten the grip of the jaws of the said bar.

5. The combination, with a rail, and a tie arranged under the rail, of abar arrangedupon the tie at one side and longitudinally of the rail,which bar is attached to the tie and has -a wedge-forming member whichprojects in the direction in which the rail tends to creep and isarranged with its larger end in front, which wedge-forming member bearsagainst the adjacent longitudinal edge of the base of the rail, andmeans whereby the said wedgeforming member is caused to more tightlygrip the rail by any tendency of the rail to creep.

In testimony whereof I sign the foregoing specification in the presenceof two witnesses.
